I found this info on the Moms panel:
I've found free wifi at three of the four Walt Disney World theme parks:
Epcot - Futureworld at Innoventions East
Epcot - Lotus Blossom Cafe, stronger signal in the back
Hollywood Studios - stand near Sorcerer's Hat on the Brown Derby side
Magic Kingdom - stand outside City Hall
If you widen your net, you'll be victorious at the following places:
ESPN Wide World of Sports
Boardwalk boat loading area outside of Boardwalk resort
Beach Club lobby
Contemporary - outside of gift shop area
Coronado Springs lobby
Grand Floridian lobby
Orlando International Airport
Downtown Disney - DisneyQuest
Downtown Disney - Wolfgang Pucks Express
Downtown Disney - Sosa Family Cigar Co. (signal even strong outside)
Downtown Disney - outside House of Blues (several)
And here is to hoping for FREE WIFI to extend to the MODERATE (and Value) resorts by next fall! As it seems to be still Free at the Deluxe's!
